• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang ((ma hoi) or (lai hoi)). ((hieu va) OR (hieu qua)) cao xuc va thanh hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang ((ma hoi) OR (lai hoi)). ((hieu va) OR (hieu qua)) cao xuc va thanh hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang ((ma hoi) or (lai hoi)). ((hieu va) OR (hieu qua)) cao xuc va thanh hai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang ((ma hoi) or (lai hoi)). ((hieu va) OR (hieu qua)) cao xuc va thanh hai cua tre*.
